GEOCHEMICAL MODEL: CRUST: aluminium silicates, Continental (heterogeneous, granite is abundant) Oceanic (homogeneous, basalt mainly) MANTLE: igneous rocks rich in iron and magnesium silicates. Mainly peridotite. The MANTLE has been traditionally divided into: upper mantle transition zone (denser materials due to higher temperature and pressure) lower mantle. but this layers do not have significant differences in chemical composition, the differences are of state and behaviour CORE: almost pure

Levels of organization
All living things have a structural and functional organization. Going from the list complex to the most complex:
Atom: The smallest component of the chemical elements that make up living thing(bioelements) primarily carbon(C), oxygen(O), hydrogen(H), nitrogen(N), phosphorus(P), sulfur(S), calcium(Ca), magnesium(Mg)and sodium(Na).
Molecule: A group of two or more atoms joined together chemically. The molecules that make up living things are called biomolecules.
